I'll try that!

[SlotStox#53]

A thorough epoxy job on the windings will hold the lamimations together for drill balancing.

 

I destroyed a Pittman DC-65-6V arm by attempting to drill balance it without epoxying the windings.....once. After that I always heavily epoxy coat all the windings and go over it with a heat gun, CAREFULLY! The heated epoxy really soaks into the windings. Any extra epoxy is simply wiped off. All of this must be done pretty quickly as heating the epoxy does cause it to thin out and flow for a minute or two but then that heat accelerates the curing process and it sets up fast.

Sounds like a soild way to prevent the lams from moving, thanks for all the advice Don & Rick

 

The dremel idea sounds ok Steve if it was done in '66... would of thought it would come out just like Champions grind balancing.

[Hworth08]

A Dremel can not handle grinding a stack. I can duplicate a Champion grind using a 4 inch, pretty fine grinding rock turned in a drill press. A person has to press pretty hard, probably around 30 pounds of pressure to make the grind and it's not the safest process.

Seems like one of the old Champion gang retained their grinder but not sure. I would guess the Champion grinder was something like a valve seat grinder with a swivel fixture to hold the arm. They did a masterful job of cutting very close to the wires sometimes.

I'm guessing whatever they used the armature was fixed and the grinding wheel moved toward the stack.

I sent my arms to Alpha. Paul varnished the windings and drill balanced it. He could not cut the com tho,due to the plastic edging on both sides of the com.

[Bill from NH]

John, try polishing the comm with 2000 grit wet or dry paper. That might be the best you can do.

Update

 

The 2 motor brackets that Pablo very kindly donated arrived   Thank you Pablo

 

 

one Brass one

 

    

 

and a steel one

 

    

 

 

Both fit the 6001 very well with the bearing hole perfect with just a very small clearancing with the brass one as the motor is a fairly tight fit.

Steel one is pretty much level with the bottom of the motor , plus got smaller axle holes so will need just a little opening up for axle tubing.

 

Now I have the all important motor bracket it's decision time as to which one to use   Both fit, both will do the job, brass one may accept bearing cups... Hmmmmm

 

 

Any suggestions?

 

*To be continued !

 

 

[slotcarone]

Looks like the brass bracket will accept bushings or bearings in the holes the way it sits. Of course there is no way to know the hole size from the picture!!

[SlotStox#53]

Forgot to put that Mike , good guess on the hole size , 1/4" so regular bearings/bushings will fit.

[SlotStox#53]

The steel bracket is being brought into service on this car

 

 

 

 

 

 

Just a quick opening up of the axle holes & they were perfect for 5/32 tubing, got both front & rear tubing cut ,although widths will change as I've ordered some Russkit repops to fit some BWA Russkit Porsche 906 inserts in , make the Porsche really stand out

 

No working out of main rail lengths yet as I don't have the body yet   unless someone knows the wheelbase of the Russkit Porsche 906 bodyshell ?

 

 

 

brass tubing or rod chassis? Hmmmmm to the design bench !

 

 

 

 

[Pablo]

Not really a lot you can do without the body, eh ?

What is the body plan ?

[SlotStox#53]

Was going to get an original Lancer 906 shell but Rick said that it was narrower in width than the Russkit one. So looking on Tom Andersen's site he pulls both Lancer and Russkit versions

gonna order some shells from him.

 

Can sort out the endbell screws on the 6001 to countersink the bottom one to get the motor flat & at least solder in the rear tube . It's a start   Make some Loooong main rails and attach them at the rear leave em long at the front !

[dc-65x]

You'll need to set not only the wheelbase but the guide lead, chassis width and pin tube body mount locations.

Much patience i have hmmmmmmmmm *best Yoda voice*

 

Yep all of those dimensions too Rick

[SlotStox#53]

Some progress but all behind the scenes   In the meantime here's what Team Pittman intends to wheel off the trailer /extract from the slotbox!

Tom Andersen has not yet responded, Paul.

Maybe today ? I hope.

[SlotStox#53]

Ok Pablo, no worries

[Jairus]

I just LOVE "Talbot" mirrors!
Have a pair on my '58 wagon by the way.

Nice choice of body there Paul. Truescale has the best 906 in my opinion.  Plus interior....

[SlotStox#53]

Thanks Jairus , love those mirrors too!
Remember seeing your cool '58 in an older post,nothing like the older cars

[mdiv]

Paul,

 

If Tom Andersen doesn't respond, try TrueScale Products - they have wonderful repop Russkit bodies - Lotus 40, Chap 2D, McLaren and Chap 2.  They come with Vinyl Mask, and beautiful interiors!  Just need a Head (can use one off a champion bust).

 

 

I have one of the chap 2Ds that I'm going to put over an AMT repop frame by Professor Motor, with Professor Motor Chap setscrew wheels (have any of you played with these?  Any suggestion of tires?  http://www.professor...-p/pmtr1112.htm)

 

Mikey

[SlotStox#53]

Good luck with the Chap project Mikey

 

have looked at those very wheels to go with a Monogram Chap 2D kit I have ,(was also looking some original Cox Chappy wheels too)  not taken the plunge though yet so have no clue over tires! Although checking the noted Dia. seems they are roughly the same size as the Russkit repop rear wheels .if that's any help? Never used wheels this size before so apart from slapping a sponge donut on em I dont know on available urethane tires.

[Mark Johnson]

If you want to verify that the arm is indeed a X arm it will read about .3 ohms pole to pole , the standard arms are much higher reading .

[SlotStox#53]

Progress! Well ........... sort ..... of

 

Russkit repop wheels , Porsche 906 interior with Russkit drivers head... all ready to go body,wheel inserts & inlet stacks to come!

 

 

 

 

Kind of like the F1 teams where they ship off their latest aero package & it arrives late "ish" to the track

 

*chassis design geeks are feverishly burning the midnight oil to thrash out a design*

[SlotStox#53]

Another piece of the puzzle arrived today !

 

NOS Auto Hobbies front tires   Don't know if they're the "Exact" ones used in the series but at 1/4" wide, 7/8" dia & .500 internal fit like a glove on the Russkit repop. Plus the right size for the rules and are Auto Hobbies tires as named in the tech sheets. So when I saw them it was an instant "yes"

 

 

 

more to come !

[Pablo]

They look perfect.

[Steve Okeefe]

Paul E.,

 

Yes they are just fine! 

 

I fact I'd like to ask... are they an ebay purchase or is somebody selling these retail?
